I have a PC/box with 5 disks in it that I am using as a fileserver and
I recently upgraded some hardware and installed FreeBSD 7.0-RELEASE.
Previously I had a RAID PATA IDE controller on the motherboard (was
not using RAID functionality though), but I when I upgraded I had to
use a PCI IDE controller, due to the lack of PATA ports on the new
motherboard.
Now when I am attempting to write files, or do anything more than just
browse filesystems on the drives ad4-ad7, I get multiple occurrences
of the errors below. After these errors occur the kernel panics and I
need to perform a hard reset to get the server back up again.
